MACHINE FOR BRINGING PASTE SUBSTANCES INTO CONlCAL FORM.

SPECIFICATION forming part of Letters Patent No. 276,096, dated April 17, 1883, Application tiled December 5, 1882. (X0 model.)

Be it known that [,GEonen W. Tnonms, of the city of Baltimore, and State of Maryland, have invented certain Improvements in an Apparatus for Producing (Jones from a Semi-Fluid Body, of which the following is a specification. H

Thisinvention relates to an apparatus whereby chalk mixed with water, so as to produce a semi-liquidwbody isdeposited on asuitable tray in independent and isolated drops of conical form; and it consists in the peculiar construction and arrangement of the various parts of the apparatus, as will hereinafter fully appear. In the description of theinvention which follows, reference is made to the accompanying drawings, forming a part hereof, and in which- Figure I is an exterior side view of the apparatus. Fig. II is an end view of the same. Fig. III is a plan of the apparatus. Figs. IV to IX, inclusive, are details of the invention on an enlarged scale. Fig.X illustrates the form of the completed cones.

Similar letters of reference indicate similar parts in all the views.

A is a hopper of conical tapering form, scoured to a wheeled frame, B, which may be of any suitable design. The wheeled frame B rests on a track, at, extending transversely of a wheeled carriage, G. The carriage 0 runs on a track, I), placed lengthwise of a table, D. The lower end of the hopper A, which is flattened, is provided with a removable plate, E, having a system ofconical thimbles, c, therein for discharging the contents of the hopper A. Discharge from any or all of the thimbles 0 may be prevented by the introduction of a slide, (1, in a slot, 6, extending lengthwise of the plate E. (See Figs. I, IV,V,VI, and VIII.) The thimbles are independently adjustable in size at their larger end by means of keysf, inserted in slots g. (See Fig. VIII.)

F is a removable tray to receive the discharge from the thimbles c.

Parts of the invention not yet alluded to will be described and their uses set forth in the description of the operation of making chalk cones which follows. i v

The various parts of the apparatus being arranged as shown in the drawings, Figs. I, II, and III, with the plate E in position and the slide (Z covering the conical thimbles, prepared chalk and water are mixed in a tank to the proper degree of fluidity, and then introduced to the hopper A. The slide (1 is then withis carried along the track I) a short distance by hand, and then stopped until a second dep osition of chalk takes place; and this oper-' ation is continued until the carriage supporting the hopper anti its attachments has traversed the full length of the tray F. The slide 6 dis now replaced and the hopper and car riage returned to theiroriginal positions. The wheeled frame B, carrying the hopper A, is next moved transversely of the carriage U a distance slightly exceeding the width of the series of cones deposited, and after the slide d is withdrawn the operation of depositing the chalk in drops is repeated. The slide is now replaced, which prevents further discharge of the chalk until the filled tray is removed and 7 replaced by an empty one. As the weight of the chalk mixture in the hopper A is reduced by its deposition on the tray, the drops have a tendency to diminish in size toward the end of the operation. the reduced head by means of a damper or valve, G. operated by a hand-Wheel, H, as will be readily understood. To effect the proper position of the hopper A- transversely of the tray F, I cut in the upper face of the car- 8;

riage G notches h, and provide the frame B with pivoted bars i, connected together by a wire, it, running over a sheave or pulley, Z. These bars t' are forced in the notches h by means of a spiral spring, m, and when the 9:

frame is moved to its proper position the bars i enter the notches h and hold the hopper firmly in place. When it is necessary to ad'- just the hopper the bars t are drawn from the notches h by means of a pivoted handle, a, 5

attached to one of the said bars by means of a wire or cord, 0. The chalk, in leaving the thimbles 0, assumes a shape shown in Fig. IX; but as the pointed end of the drop comes in contact with the tray it is flattened, and a I00 cone produced corresponding with the one shown in Fig. X. To prevent clogging of the I counteract the effect of track I) by particles of chalk, I cover the same with a belt, 1), having apertures for the wheels of the carriage 0. (See Figs. I and III.) The height of the cones depends upon the distance between the lower end of the thimbles and the tray, and this distance is made alterable by constructing the frame B in two parts, as shown in the drawings, and connecting the said parts by means of bolts g. It will be understood that the transverse movement of the hopper is only necessary when two rows of cones are to be deposited.

I am aware that, in the manufacture of dropcandy, machines have been used in which are combined a wheeled pan to hold the confectioners compound, having lateral dischargeapertures at its lower end, a sliding cut-off adapted to pass over the said openings, and mechanism whereby the said cnt-ofi' is made to have a reciprocating movement to shear ed the stream of compound flowing from the said lateral apertures and form drops; but I am not aware that prior to my invention a taperinghopperhavingcontrollabledischarge-openings at its lower end has been combined with a guiding-track and a removable tray, sub stantially as described.

I therefore claim as my invention 1. An apparatus for producing cones from a semi-liquid body, which has the following essential elements in combination, viz: a taperin g hopper having a series of discharge-apertures at its smaller end, with means for closing the said apertures, and erected on a wheeled carriage, a table having a track running longitudinally thereof, fitted to receive the wheeled carriage, and a removable tray adapted for location between the rails of the said track, substantially as specified.

2. In a machine for producing cones from a semi-liquid body, a tapering hopper for the said liquid body, having a removable plate at its smaller end, fitted with conical thimbles for discharging the said hopper of its contents, and means for closing the said thimbles to pre vent the discharge, substantially as specified.

3. In a machine for producing cones from a semi-liquid body, a tapering hopper for the said body, havinga removable plate fitted with discharge-thimbles, as described, and means for separately controlling the size of the said thimbles, substantially as specified.

4. In combination with the table D, having the track b and the wheeled carriage O, the endless belt p, having apertures therein for the wheels of the said carriage, substantially as and for the purpose specified.
